Advanced Patterns — quiz

You add a custom command `cy.loginAsAdmin()` in TypeScript via `Cypress.Commands.add`. The IDE doesn't autocomplete it on `cy.`. What's missing?

• You forgot to restart the IDE
• You need to extend the `Cypress.Chainable` interface in a `.d.ts` file (or in support/commands.ts) to declare the new command's signature
• Cypress doesn't support custom commands in TypeScript
• You need to add the command to cypress.config.ts
